mtd: nand: Force omap_elm to be built as a module if omap2_nand is a module
This commit adds a hidden option to build the omap_elm as a module, if omap2_nand is a module (and similarly in the built-in case). This fixes the following build error when omap2_nand is chosen built-in, and omap_elm is chosen as a module: drivers/built-in.o: In function `omap_nand_probe': drivers/mtd/nand/omap2.c:2010: undefined reference to `elm_config' drivers/mtd/nand/omap2.c:1980: undefined reference to `elm_config' drivers/mtd/nand/omap2.c:1927: undefined reference to `elm_config' drivers/built-in.o: In function `omap_elm_correct_data': drivers/mtd/nand/omap2.c:1444: undefined reference to `elm_decode_bch_error_page' Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
